Abstract
Paclobutrazol treatment combined with IBA and urea-phosphate significantly enhanced the rooting of softwood peach (Prunus persica L. Batsch) ‘Maravilha’ cuttings. Application of paclobutrazol to the mother plants 8 months before removal of cuttings was more effective than application directly to the cuttings. The survival rates of rooted cuttings obtained from paclobutrazol-treated plants were significantly higher than those obtained from untreated plants. Chemical names used: 1H-indole-3-butyric acid (IBA), β-[(4-chlorophenyl)methyl]-α-(1,1-dimethylethyl)-1H-1,2,4-tria-zole-1-ethanol (paclobutrazol).
Abstract
Ethylene gas promoted abscission of mature-green fruits of olive (olea europaea L.) but did not induce endogenous ethylene production. Ethylene readily penetrated and moved through olive fruits. Mature-black olives did not respond to ethylene.
